Hi again all,

This may well be a silly question, but I thought it best to ask rather than risk wasting money.

I'm currently buying-in all the kit I need to retrofit the sat nav system into a 2001 4.4 sport that's never had it, only has business radio (with tape) and 6-disc non-mp3 changer.

So far I've got myself a wiring loom from an X5 that had an '04 build date and a 'dec 05 (i forget the part number, but can soon get it - I'm not at home just now) BM54 radio unit (the model that supports ID3 tags).

Now, I'm definately going to opt for a MKIV dvd Nav comp - if it has older software then I'll update it myself (well, I'll try lol) later. But as for the screen .....are all the widescreen bordmonitors the same, can I just buy any one? In other words, does it matter what year or part number I get? Does it carry any software itself?

Thanks in advance guys.
Dave
